High Roller 2 EXO's super loose on the rim?

Anyone else have High Roller 2's in the EXO sidewall? I have one that is so loose, its hard to keep it on the rim for inflation and I'm wondering if they are are just looser than the EXO DHF's I've had of if they had a bead issue? Have worn out about 6 DHF EXO's and was hoping the HR2's would be similar.

Update: Been using Stan's Flow rims and finally having luck keeping the tire on mounting it ghetto-tubless using a BMX tube. 2 weeks of pretty technical riding and its still fine. But just got a brand new DHF, way tighter on the rim and works tubless with no issues.
